1. A battery depletion prevention system for a vehicle, the battery depletion prevention system comprising:
a power-supply monitoring apparatus configured to monitor a value of a current flowing through a battery;
a first switch provided between the battery and an in-vehicle apparatus and not between the battery and a communication apparatus; and
a turn-off control apparatus configured to:
determine, based on the value of the current detected by the power-supply monitoring apparatus, whether current value abnormality is occurring;
upon determining that the current value abnormality is occurring, turn off the first switch and thereby achieve a first coupling state; and
upon determining that the current value abnormality is no longer occurring in the first coupling state, perform abnormality notification to a user terminal of a user of the vehicle via the communication apparatus, wherein the user terminal is not part of the vehicle and is configured to externally interact with the vehicle.
